Mamma Mia! celebrated its 27th birthday on April 6, 2026, and is the third longest running West End musical of all time.
Since premiering in London’s West End in 1999, the smash-hit has become a global phenomenon, with more than 70 million people having seen it worldwide. The musical returned to Broadway, at the musical’s original home, the Winter Garden Theatre, on August 2, 2025, for a limited six-month run until February 1, 2026.
Originally opening in New York in 2001, the production played for a record-breaking 14 years at the Winter Garden and then at the Broadhurst Theatre, making it Broadway’s ninth longest-running show of all time. A new UK Tour began on October 24, 2025, and will run through to January 30, 2027.
The sunny, funny tale of a mother, a daughter and three possible dads on a Greek island idyll, all unfolding to the magic of ABBA’s timeless pop masterpieces, has been seen in more than 50 productions in 16 different languages, grossing more than £4.5 billion at the box office, and turned into two record-breaking movies.
Mamma Mia! originally opened in London at the Prince Edward Theatre on April 6, 1999, before transferring to the Prince of Wales Theatre in 2004, and then to the Novello Theatre in 2012.
With music & lyrics by Benny Andersson & Björn Ulvaeus, Mamma Mia! is written by Catherine Johnson, directed by Phyllida Lloyd and choreographed by Anthony Van Laast. The production is designed by Mark Thompson, with lighting design by Howard Harrison, sound design by Andrew Bruce & Bobby Aitken, and musical supervision, additional material and arrangements by Martin Koch.
Mamma Mia! is produced by Judy Craymer, Richard East & Björn Ulvaeus for Littlestar in association with Universal Music Group.
